Is it bad to replace one breast due to a capsule contracture? My other breast is fine

From a technical standpoint it is better to replace both implants so the surgeon can control the cosmetic appearance.

If you are otherwise happy with the implants and size it is fine to replace just the implant for the breast with capsular contracture. Patients often will take the opportunity to make changes to their implants if they are wanting something different if they have to address capsular contracture anyway.

Removal of breast implants, intact or ruptured, may have positive implications if patients are symptomatic. A constellation of symptoms associated with breast implant illness, and autoimmune disease are considered when treating patients who have breast implants and are concerned about foreign body reaction. In our office, we begin this journey with a consideration of symptoms and exclusion of obvious autoimmune problems. In many of our patients, en bloc removal of breast implants with capsulectomy is important and beneficial. Further clinical evidence about breast implant illness is evolving and will continue to guide treatment. I would suggest removal if there is a possibility of foreign body reaction.

Thanks for your question.  I think that you have a few options. Yes, you can just have the side with CC addressed. The potential issue with this is that the newly operated breast may heal a bit differently that the non operated breast. When correcting CC, I discuss with my patients the option of exchanging both implants, as sometimes that will allow me the option to create the best symmetry possible.  As far as the use of textured implants, some studies have shown that the use of textured implant may decrease the risk of CC. I am assuming that you have smooth implants now.  Obviously, your left breast has healed without issue, so the smooth implant itself has not "caused" the CC.  Usually, CC is a result of some degree of bacterial contamination, usually from the breast tissue itself, or implant rupture.  I would discuss the pros and cons of one side vs both sides and textured vs smooth with your PS. If your implants have been in for many years, it may make sense to replace both.  Best Regards.

If one breast is doing well, then leave it alone. Every surgery has risks. I would just replace the encapsulated side unless your doctor is choosing a different shaped implant.
